I was at Carter today, and saw a rune on the lot that had the key in it so I helped myself to a little fire up. I must say I was a little surprized at the sound of them. I though they would have sort of a "chopper" loudness to them, but there pretty dam quiet! The sound of them reminds me of the old cavalier Z24 V6. just a mellow rumble.
I actually kinda dig the rune, but doubt I would ever buy one.
